First step is 5+7(36x+8y) because you have to distribute
Can’t answer this as it gives no information?
13+8n=-3
<em>Subtract 13 from both sides</em>
8n=-16
<em>Divide both sides by 8</em>
n=-2
Answer:
The solution for the system of equations is
x=2,y=−2
Explanation:
4x−3y=14.....equation (1)
y=−3x+4.....equation (2)
Solving by substitution
Substituting equation 2 in equation 1
4x−3⋅(−3x+4)=14
4x+9x−12=14
13x=14+12
13x=26
x=2
Finding y by substituting x in equation 1
4x−3y=14
4⋅2−3y=14
8−3y=14
8−14=3y
3y=−6
y=−2
