1/5(a+10)=-3 I need to find the the value of and and I need the steps please and thanks

How many solutions does the nonlinear system of equations graphed bellow have?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Can someone me with my math problems i have a bunch. i will give brainliest and lots of pleeeaaasssee
