Answer:

34

Step-by-step explanation:

4x+3x-8=90

so lets start by solving this

Let's solve your equation step-by-step.

4x+3x−8=90

Step 1: Simplify both sides of the equation.

4x+3x−8=90

4x+3x+−8=90

(4x+3x)+(−8)=90(Combine Like Terms)

7x+−8=90

7x−8=90

Step 2: Add 8 to both sides.

7x−8+8=90+8

7x=98

Step 3: Divide both sides by 7.

7x

7

=

98

7

x=14

Answer:

x=14

so plug this in and you get 3*14 -8

this equals 34

Answer:

It is 34 degrees

Step-by-step explanation:

Step 1:  Make an equation

[tex]4x + 3x - 8 = 90[/tex]

Step 2:  Combine like terms

[tex](4x + 3x) - 8 = 90[/tex]

[tex]7x - 8 = 90[/tex]

Step 3:  Add 8 to both sides

[tex]7x - 8 + 8 = 90 + 8[/tex]

[tex]7x = 98[/tex]

Step 4:  Divide both sides by 7

[tex]7x / 7 = 98 / 7[/tex]

[tex]x = 14[/tex]

Step 5:  Find the measure

[tex]3x - 8[/tex]

[tex]3(14) - 8[/tex]

[tex]42 - 8[/tex]

[tex]34^o[/tex]

Answer: It is 34 degrees
