Remove the bracket and simplify: 3x ( 2y - 7z)

• 5xy - 10xz

• 6xy - 21xz

• 6xy + 21xz

• 5xy - 21xz

if x = 3 and y = 2, the value of 2x + y is:

• 8

• 6

• 7

• 4

solve: x + 7 = 9

• x = -2

• x = 16

• x = -16

• x = 2

solve: 2y - 5 = 13

• y = 18

• y = 9

• y = -9

• y = -18

solve: 7a = -42

• a = 35

• a = 42

• a = 7

• a = -6
