Question

Solve the following pairs of lineas equation by the
elimination method.
3x+4y=10
2x-2y=2
​

Answer 1

Answer:

x = 2

y = 1

Step-by-step explanation:

We have to multiply one equation by a number that the value of x or y match with another equation.

3x+4y=10

2(2x-2y=2) = 4x-4y=3

3x+4y=10

4x-4y=3

Now we have to add these 2 equation together, and +4y and -4y will be removed. So,

7x = 13

x = 1.85, if we simply it, it will be 2

so now we have the value of x, we will use in one equation.

3x+4y=10

3(2)+4y=10

6+4y=10

4y=10-6

4y=4

y=1

hope the answer will be correct and you got it
