Question

Solve 16(3x-5) -10(4x-8) = 40

Answer 1

Answer:

x = 5

Step-by-step explanation:

Step 1: Multiply out the brackets

48x - 80 - 40x + 80 = 40 → negative + negative = positive [-10 x -8]

Step 2: Simplify                          

8x = 40 → collect like terms

Step 3: Solve

x = $\frac{40}{8}$

x = 5

Answer 2

Answer:

x = 5

Step-by-step explanation:

Step 1: Multiply out the brackets

48x - 80 - 40x + 80 = 40 → negative + negative = positive [-10 x -8]

Step 2: Simplify                          

8x = 40 → collect like terms

Step 3: Solve

x = (40/8)

x = 5
