Answer:

Explanation:

first step: 0.5 * x

second step: 3* (0.5x) = 1.5x

third step: (1.5x)^2

fourth step: (1.5x)^2 + 1 = 50

(1.5x)^2 + 1 = 50 Subtract 1 from both sides

(1.5x)^2 = 49 Take the square root of both sides

1.5x = sqrt(49)

1.5x = +/- 7

1.5x = +7

x = 7/1.5

x = 4.67

1.5x = - 7

x = - 7 / 1.5

x = - 4.67
