Question

Solve each equation.
2x=5

y+1.8=14.7

6=12z

314=12+w

Answer 1

2x = 5 : x = 5/2 (as a decimal : x = 2.5)

y + 1.8 = 14.7 : y = 12.9

6 = 12z : z = 1/2 (as a decimal : z = 0.5)

314 = 12 + w : w = 302

Explanation:

2x + 5 : 2x/2 + 5/2 ; x = 5/2

y + 1.8 = 14.7 : y + 1.8 - 1.8 = 14.7 - 1.8 ; y = 12.9

6 = 12z : 6/12 = 12z/12 ; z = 1/2

314 = 12 + w : 314 -12 = 12 + w - 12 ; w = 302
