5(X-7)=26.5 4(X+8.2)=40.8 (X-0.52)÷4=1.12 1.5×(X-8)=60求方程的解
问题描述:
5(X-7)=26.5 4(X+8.2)=40.8 (X-0.52)÷4=1.12 1.5×(X-8)=60
求方程的解
答
5(X-7)=26.5
x-7=5.3
x=12.3
4(X+8.2)=40.8
x+8.2=10.2
x=2
(X-0.52)÷4=1.12
x-0.52=1.12*4
x-0.52=4.48
x=5
1.5×(X-8)=60
x-8=60÷1.5
x-8=40
x=48
答
5(X-7)=26.5
x-7=5.3
x=12.3
4(X+8.2)=40.8
x+8.2=10.2
x=2
(X-0.52)÷4=1.12
x-0.52=4.48
x=5
1.5×(X-8)=60
x-8=40
x=48
