Question

solve each of the following equations by systematic method and verify the result: i) 8x+8=80
ii) 13=4m÷10-7
iii) 16 (3x-5)-10(4x-8)=40
​

Answer 1

Answer:

8x+8=80

8x=80-8=72

X=72/8

X=9

13=4m÷10-7

13+7=4m÷10

20×10=4m

200\4=m

50=m

16(3x-5)-10(4x-8)=40

48x-80-40x+80=40

48x-40x-80+80=40

8x+0=40

X=40/8

X=5
