Question

Solve for x: 5x+3+8x-4=90

Answer 1

x = 7

Step-by-step exxplanation:

5x + 3 + 8x - 4 = 90

5x + 8x = 90 - 3 + 4

13x = 91

x = 91/13

x = 7

probe:

5*7 + 3 + 8*7 - 4 = 90

35 + 3 + 56 - 4 = 90

Answer 2

`x = 7`

Explanation:

We can solve the equation
`5x+3+8x-4=90` by isolating the variable x on one side. To do this, we must simplify the equation.

`5x+3+8x-4=90`

Combine like terms:

`13x - 1 = 90`

Add 1 to both sides:

`13x = 91`

Divide both sides by 13:

`x = 7`
