• p-qr
• p- q⁄ᵣ

Use wordsto describe the algebraic expression 15- (2x+3).

• Subtract two times of x from 15, then add 3 to the result.
• Two times of x is added to 3, then subtract 15 from the result.
• Multiply x by 2, add 3 to the product and then subtract this sum from 15.
• Subtract 3 from the product of x and 2, then subtract the result from 15.

p×q-r÷s=

• pq- ˢ⁄ᵣ
• ᵖq- ʳ⁄ₛ
• pq- ʳ⁄ₛ
• p(q-ʳ⁄ₛ)

Which of the following are like terms of -²ᵐ⁄ₙ?

• -²ᵐ⁄ₙ
• -2÷m
• n÷4m
• -m÷(-8n)

Which of the following equations has solution x=0?

• x+2=0
• 2x-3=0
• 2x+1=7
• 3x-2=-2

When solving the equation 3(x+3)- 5(2x+1)= 6x-1, the left-hand side of the equation can be written as

• 13x+14
• -13x-4
• -7x+4
• -7x+5

If 1 is added to both sides of the equation 4y-5 = y-1, then

• the two sides are not equal.
• the value of y remains unchanged.
• the value of y becomes larger.
• the value of y becomes smaller.

When k = -5, which of the following is not correct?

• k + 6 = 1
• -2k= 10
• k + 1 = -4
• k-2 = 7

To solve ⁵ˣ⁺²⁄₄ -⁷ˣ⁻⁵⁄₅ = 0, the first step is to multiply both sides of the equation by

• the H.C.F. of 4 and 5
• the L.C.M. of 4 and 5
• 7x - 5

To solve ½ (ˣ⁄₂ - 1) - 1 = 5, which of the following should be multiplied to both sides of the equation to cancel the denominators?

• 2
• 4
• 5
• 6
