[tex]20x + 35y = 5(4x + 7y)[/tex]

we are given

20x + 35y =? (? x + 7y)

Let's assume

'a' in first question mark

and

'b' in second question mark

so, we get

[tex] 20x+35y=a(bx+7y) [/tex]

now, we can distribute it

[tex] 20x+35y=abx+7ay [/tex]

now, we can compare both sides

and we get

[tex] 7a=35 [/tex]

[tex] a=5 [/tex]

now, we can find b

[tex] 20=ab [/tex]

[tex] 20=5b [/tex]

[tex] b=4 [/tex]

so, we get

[tex] a=5 [/tex]

[tex] b=4 [/tex]

we can write it as

[tex] 20x+35y=5(4x+7y) [/tex]..............Answer
