Solve the system of linear equations by substitution.<br> 2x-y=3<br> x+5y=14
Arturiano [62]

Answer:

x= 29/11 or y= 25/11

Step-by-step explanation:

2x - y= 3 ...........equation 1

x + 5y= 14 ............equation 2

Make x the subject of the formula in equation 2

x= 14 - 5y ..............equation 3

Substitute x=14 - 5y in equation 1

2(14- 5y) - y=3

28 - 10y - y=3

Collect like terms

-10y - y=3 - 28

-11y= -25

divide both sides by coefficient of y

-11y/-11 = -25/-11

y= 25/11

Substitute y= 25/11 in equation 3

x=14 - 5(25/11)

x= 14 - 125/11

x= 29/11

1/6m=5/8<br> i can't slove this question<br> 8th Grade Math
murzikaleks [220]

we are given

\frac{1}{6} m=\frac{5}{8}

Since, we have to solve for m

so, we will try to isolate m on anyone side

so, firstly , we will get rid of 1/6

so, we can multiply both sides by 6

6*\frac{1}{6} m=6*\frac{5}{8}

m=6*\frac{5}{8}

now, we can simplify right side

m=3*\frac{5}{4}

now, we can multiply them

and we get

m=\frac{15}{4}...........Answer
