Question

Please help i need to solve for m and n

Answer 1

x=22

because…

2x-26+7x+8=180
9x-18=180
9x=198
x=22

Answer 2

`\Longrightarrow:\boxed{\sf{x=22}}`

Explanation:

To find the value of x, isolate it on one side of the equation.

Given:

`\Longrightarrow: \sf{m: (2x-26)}\\\\\\\Longrightarrow: \sf{n: (7x+8)}`

`\Longrightarrow: \sf{2x-26+7x+8=180}`

First, combine like terms.

`\Longrightarrow: \sf{2x+7x-26+8=180}`

Add the numbers from left to right.

2x+7x=9x

`\Longrightarrow: \sf{9x-26+8=180}`

-26+8=-18

`\Longrightarrow: \sf{9x-18=180}`

Add by 18 from both sides.

`\Longrightarrow: \sf{9x-18+18=180+18}`

Solve.

Add these numbers from left to right.

180+18=198

`\Longrightarrow: \sf{9x=198}`

Divide by 9 from both sides.

`\Longrightarrow:\sf{(9x)/(9)=(198)/(9)}`

Solve.

Divide the numbers from left to right.

198/9=22

`\Longrightarrow: \boxed{\sf{x=22}}`

• Therefore, the correct answer is x=22.
