Solve using substitution x=(3y+1) and x+4y=15

natka813 [3]

The solution is: x= 7 and y = 2

Step-by-step explanation:

Given equations are:

$x = 3y+1\ \ \ \ Eqn\ 1\\x+4y = 15\ \ \ \ Eqn\ 2$

Putting x = 3y+1 in equation 2 from equation 1

$3y+1+4y = 15\\7y+1 = 15\\$

Subtracting 1 from both sides

$7y+1-1 = 15-1\\7y = 14$

Dividing both sides by 7

$\frac{7y}{7} =\frac{14}{7}\\y = 2$

Putting y=2 in equation 1

$x = 3(2) +1\\x = 6+1\\x = 7$

Hence,

The solution is: x= 7 and y = 2

What is 3 1/2 multiplied by 2 1/4 as a mixed number or fraction

Nataly [62]

Hey there!

$3\frac{1}{2}$ × $2\frac{1}{4}$

$3\frac{1}{2}$ = $\frac{7}{2}$

$2\frac{1}{4}$ = $\frac{9}{4}$

$\frac{7}{2}$ × $\frac{9}{4}$

$7\times9 = 63$

$2\times4 = 8$

$\boxed{Answer: \frac{63}{8} ; 7\frac{7}{8} }$

Good luck on your assignment and enjoy your day!
