Answer:
5x - y = 10x + 3y = 4
5x - y = 4..... 1
10x + 3y = 4.....2
multiply by -2 in eq 1 in both sides
-10x + 2y = -8
10x +3y = 4
eliminate one variable by adding the equations
5y = -4
y = - 4/5
sub the value of y in..1
5x - y = 4
5x + 4/5 = 4
5x = 16/5
divide by 5 on both sides
x = 16/25
(x ; y)
(16/25 ; -4/5)
Answer:
135 is the correct answer
Step-by-step explanation:
6x^2-3x
substitution
x=5
6* (5*5) -3*5
6*25-3*5
150-15= 135
Just multiply it so multiply 59.89 x 4 and then for number 8 multiply 88.70 x 4
