Question

3x-2y=8 4x+3y=5 Solve the simultaneous equation by substitution method

Answer 1

Step-by-step explanation:

Step 1 :3x-2y=8

3x=8+2y

X=2y+8/3-------------------a

Putt the value of x in this equation :

4x+3y=5

4(2y+8/3)+3y=5

8y+32/3+3y=5

8y+32+9y=5*3

8y+32+9y=15

17y+32=15

17y=15-32

17y=-17y=-17/17=-1

Putt the value of y in equation a:

X=2(-1)+8/3

X=-2+8/3

X=6/3

X=2
