Which statement correctly explains how Marì could find the solution to the following system of linear equations using elimination?
2f-5g=-9
-7+3g=4

Given that,

The equations : 2f-5g=-9  and -7f+3g=4

To find,

The solution of the above equations.

Solution,

We have,

2f-5g=-9  (1)

-7f+3g=4 (2)

Multiply equation (1) by 7 and equation (2) by 2.

14f-35g=-63  (3)

-14f+6g=8 (4)

Add equation (3) and (4)

14f-35g -14f+6g = -63 + 8

-29g = -55

g = 55/29

g = 1.89

Put the value of g in equation (1).

2f-5(1.89)=-9

2f = -9+5(1.89)

f = 0.225

Hence, the solution of the above equations are g = 1.89 and f = 0.225.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
