Question

Solve for m. 5m + 3m - 8 = 64 a m = 9 b m = 2 c m = -2 d m = 5

Answer 1

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{m = 9}}}}}$

Option A is the correct option

Step-by-step explanation:

$\sf{5m + 3m - 8 = 64}$

Collect like terms

⇒$\sf{8m - 8 = 64}$

Move 8 to right hand side and change it's sign

⇒$\sf{8m = 64 + 8}$

Add the numbers

⇒$\sf{8m = 72}$

Divide both sides of the equation by 8

⇒$\sf{ \frac{8m}{8} = \frac{72}{8} }$

Calculate

⇒$\sf{m = 9}$

Hope I helped!

Answer 2

Answer:

$\Huge \boxed{m=9}$

Step-by-step explanation:

$5m + 3m - 8 = 64$

Combining like terms.

$8m - 8 = 64$

Adding 8 to both sides.

$8m=72$

Dividing both sides by 8.

$m=9$
