For this question what does x equal?

Hi again lol. It is complementary so it would equal to 90. The equation is 6x+1+29=90

Step-by-step explanation:

6x+1+29=90

6x+30=90

6x=60

divide both by 6

x=10

10

Hope that helped! :)

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
