3x+10y=13<br> 4(-2y+x)-9x=13

mart [117]

Answer:

$x=-9$

$y=4$

Step-by-step explanation:

$3x+10y=13$ ← Equation 1

$4(-2y+x)-9x=13\\$

By simplifying the above equation we get,

$-8y+=4x-9x=13$ (Simplifying the brackets)

$-8y-5x=13$ (By subtracting $-9x$ from $+4x$ ) ← Equation 2

Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.

Equation 1 multiplied by 5 will give,

$15x+50y=65$

Equation 2 multiplied by 3 will give,

$-24y-15x=39$

Add those together,

$15x+50y-24y-15x=65+39$

$26y=104$ (After simplifying $x$ values)

Therefor $y=4$

By substituting $y=4$ to Equation 1 we get,

$3x+10*4=13$ $3x+40=13\\3x=-27\\x=-9$

Therefor we can say,

$x=-9$

$y=4$

2y = 4x + 8 4y = 4x + 20

mars1129 [50]

<span>2y = 4x + 8 ------> y = 2x + 4
4y = 4x + 20 ------> y = x+5

2x+4 =x+5
x = 1
y=x+5=1+5=6

Check:
</span>2*6 = 4*1 + 8 , 12 =12
4*6 = 4*1 + 20, 24 =24<span>

x=1,y=6
(1,6)

2x+2y=-2<br> 3x-2y=12<br><br> What is this please

nydimaria [60]

Answer:

x=2, y=-3

Step-by-step explanation:

This type of problems is called a system of equations, or simultaneous equations.

When solving simultaneous equations, you need to first make sure you have two unknown terms of the same number but different signs - this is so one unknown cancels out because we can only solve when there's one unknown. We already have this ('2y' and '-2y'). Now we just add the 'x's, the 'y's and the numbers:

2x+2y=-2

3x-2y=12

(2x+3x)+(2y-2y)=(-2+12)

5x=10

x=2

Now that we know the value of x, use it to find y:

2x+2y=-2

2(2)+2y=-2

4+2y=-2

2y=-6

y=-3
