The value of x in this system of equations is 1.3x + y = 9y = –4x + 10Substitute 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 = –1x = 1What is the value of y?

Answer:In my opinion the answer is y = 6Step-by-step explanation:We have two unknowns from the equation therefore, two equations are needed. These equations are: 3x + y = 9  y = –4x +10   To solve for y, we first substitute the second equation to the first one. 3x + –4x +10= 9  x = 1 We substitute the value of x to either of the equations and solve for y. y = –4(1) +10  y = 6
