Question

Solve the following equations without transposing and check your result:
x+5=9
y-12=-5
3x+ 4=19
9z=81
3x+8=5x+2
5y+10=4y-10

Answer 1

Step-by-step explanation:

without transposing

for example

x+5=9

subtracting both side by -5

so we get X + 5 - 5 =9 - 5

x=4

We can check the result by putting X = 4 in equation X + 5 = 9

so lhs =rhs therefore answer verified

you can apply the same method in other question also.

Answer 2

Step-by-step explanation:

1.

=>X=5-9

=>X=4

2.

=>Y=12+5 (As Minus+Minus=Addition)

=>Y=17

3.

=>X=3×4=19

=>X=12-19

=>X=7

4.

=>Z=9÷81 (As there is only 1 number before the equal we will divide it by after equal sign number)

=>Z=9

5.

=>X=(3x+5x)-(8+2)

=>X=(8x)-(10)

=>X=2

6.

=>Y=(5y+4y)-(10-10)

=>Y=(9y)(0)

So. Hence Y=9
