Linear Systems Review- Grade 10

How many solutions ( point of intersection) are there to the following linear system?

y= 7x-4

y=7x+5

• 0

• 1

• infinite number

Translate into an algebraic equation. " Three times a number subtracted from ten is five more than seven times the number" 

• 3x-10=7x+5

• 3x-10=7x-5

• 10-3x=7x+5

• 10-3x=5-7x

Which of the following linear equation is equivalent to x-2y+2=0?

• 4y=3x+1

• 2y=-x+2

• 2x-2y+4=0

The sum of two numbers is 39 and the difference between the same two numbers is 43.  Which system below can be used to find the two numbers?

• x + y = 39
  x + y = 43
• x - y = 39
  x - y = 43
• x + y = 39
  x - y = 43
• x - y = 39
  x + y = 43
