Question 295047
y = 2x + 3
y = -x - 4
Use the substitution method

If y = 2x + 3 then replace the y in the second equation with 2x + 3
2x + 3 = -x - 4
Collect like terms
3x = - 7
x = -7/3

If x = -7/3 then substitute that value in to the top equation to find y
y = 2(-7/3) + 3
y = -14/3 + 9/3
y = - 5/3
