Answer:
x=−9 and y=8
Step-by-step explanation:
Let's solve your system by elimination.
2x+3y=6;4x−y=−44
Multiply the first equation by -2,and multiply the second equation by 1.
−2(2x+3y=6)
1(4x−y=−44)
Becomes:
−4x−6y=−12
4x−y=−44
Add these equations to eliminate x:
−7y=−56
Then solve−7y=−56for y:
−7y=−56
-7y/-7 = = -56/-7
(Divide both sides by -7)
y=8
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2x+3y=6
Substitute8 for y in 2x+3y=6:
2x+(3)(8)=6
2x+24=6(Simplify both sides of the equation)
2x+24+−24=6+−24(Add -24 to both sides)
2x=−18
2x/2 = -18/2 (Divide both sides by 2)
x=−9
Answer:
x=−9 and y=8
Answer:
x = -9
y = 8
Step-by-step explanation:
(using substitution)
4x-y = -44
4x + 44 = y
substitute (4x+44) as y in the other equation
2x + 3(4x+44) = 6
2x+12x+132 = 6
14x = -126
x = -9
then plug -9 as x into one of the equations to find y
4(-9) - y = -44
-36-y=-44
-y=-8
y=8
then check the answer by plugging in the values of x and y (-9 and 8) for x and y in one of the equations
4(-9) - (8) = -44
you get: -44 = -44, which is true, so the x and y values are correct
