You can use to first equation to find y in terms of x: x - y = -3 Subtracting x from both sides we get -y = -x - 3 Multiplying both sides by -1 gives us y = x + 3 Now plug the value for y into the second of the original equations, giving: x + 3(x + 3) = 5 ...................(1) Now you just need to solve equation (1) to find the value of x.

how do i solve for 1?

well how do i solve x+3(x+3)=5

  • kropot72
x + 3(x + 3) = 5 ...................(1) Expanding the brackets gives x + 3x + 9 = 5 Adding like terms we get 4x + 9 = 5 ............(2) Now you should be able to solve equation (2).

4x+9=5 -9 -9 4x=-4

is that right so far?

  • kropot72
Yes, 4x = -4 is correct. Now divide both sides by 4.
