Given : Given Equations are 2x+3y=16
x-4y=-3
To Find: Values of x & y
Step-by-step explanation:
- Step 1 : 2x +3y = 16 -----------> eq. 1
x-4y = -3 --------------> eq. 2
From eq.2
x-4y=-3
transposing (-4y) to L.H.S
x=-3+4y--------------> eq. 3
- Step 2 : substituting eq.3 in eq.1
2(-3+4y) + 3y = 16
-6 + 8y +3y =16
-6 + 11y =16
11y = 16+6
11y = 22
y=
y = 2
- Step 3 : Substituting y=2 in eq.3
x= -3 + 4y
x= -3 + 4(2)
= -3 + 8
= 5
x = 5
Value of x is 5 and y is 2
