Please find the value of x and y.

Sophie [7]

Answer:

x = 11

y = 3

Step-by-step explanation:

4y+1=6y-5

-4y -4y

+1 =2y-5

+5 +5

6/2=2y/2

3=y

2x-4= 18

+4 +4

2x/2 = 22/2

x=11

Answer:

$x = 1.25$

$y = 0$

Step-by-step explanation:

Given

$4x - 5y = 5$

$0.08x + 0.10y = 0.10$

Required

Determine the solution

Make x the subject of formula in: $4x - 5y = 5$

$4x = 5 + 5y$

Divide both sides by 4

$\frac{4x}{4} = \frac{5 + 5y}{4}$

$x = \frac{5 + 5y}{4}$

Substitute $x = \frac{5 + 5y}{4}$ in $0.08x + 0.10y = 0.10$

$0.08(\frac{5 + 5y}{4}) + 0.10y = 0.10$

Solve the fraction

$0.02(5 + 5y) + 0.10y = 0.10$

Open the bracket

$0.1 + 0.1y + 0.10y = 0.10$

$0.1 + 0.2y = 0.10$

Subtract 0.1 from both sides

$0.1-0.1 + 0.2y = 0.10 - 0.1$

$0.2y = 0$

Divide both sides by 0.2

$y =0$

Substitute 0 for y in $x = \frac{5 + 5y}{4}$

$x = \frac{5 + 5*0}{4}$

$x = \frac{5 + 0}{4}$

$x = \frac{5 }{4}$

$x = 1.25$

Whats the difference 5 2/7 - 3 4/7

umka21 [38]

$5 \frac{2}{7} - 3\frac{4}{7} =\frac{(5\times 7)+2}{7} -\frac{(3\times7)+4}{7} =\frac{37}{7} -\frac{25}{7} -\frac{37-25}{7} =\frac{12}{7}=\boxed{\bf{1\frac{5}{7}}}$
