Answer:

x= 6

Step-by-step explanation:

[tex]12x +4 = 10x+16 \\[/tex]

You will subtract 10x from 12x and get 2x

[tex]2x + 4 = 16[/tex]

Subtract 4 from 16 to get 12

[tex]2x = 12[/tex]

You will then divide both sides by 2

[tex]\frac{2x}{2}[/tex] = [tex]\frac{12}{2}[/tex]

x= 6

The second one is hard to read but since ∠3 is 54° you should just start from there

Hope this helps

Answer:

x = 6

Step-by-step explanation:

The Answer for the first figure:

m<5 and m<7 are equal, since they are corresponding angles. So, that means;

m<5 = m<7

12x + 4 = 10x + 16

12x - 10x = 16 - 4

2x = 12

x = 6 (when both divided by 2)
