3x + 2y = -26 ........(1)

2x - 6y = -10........(2)

Multiplying (1) by 3

= 9x + 6y = -26

Adding (1) and (2)

= 9x + 6y = -78

= 2x - 6y = -10    (+)

---------------------------

11x = - 88

x = -8

Substituting x in (2)

-16 - 6y = -10

-6y = 6

y = -1

boyakko [2]

Answer:

X=-4 last answer i got i hope it is helpful have a nice day

Step-by-step explanation:

Let's solve your equation step-by-step.

6(3x+5)=7(2x+2)

Step 1: Simplify both sides of the equation.

6(3x+5)=7(2x+2)

(6)(3x)+(6)(5)=(7)(2x)+(7)(2)(Distribute)

18x+30=14x+14

Step 2: Subtract 14x from both sides.

18x+30−14x=14x+14−14x

4x+30=14

Step 3: Subtract 30 from both sides.

4x+30−30=14−30

4x=−16

Step 4: Divide both sides by 4.

4x

4

=

−16

4

x=−4

Answer:

x=−4

krok68 [10]

Answer:

Feeds = 11.76kg

Step-by-step explanation:

Given

Field\ A= 56\%

Field\ B= The\ rest

Bag = 21kg\ feed

Required

Determine how much goats in field A, get.

To do this, we simply multiply the percentage feed received by goats in field A by the actual bags of feeds

i.e.

Feeds = 56\% * 21kg

Convert percentage to decimal

Feeds = 0.56 * 21kg

Feeds = 11.76kg

<em>Hence, goats in field A get 11.76kg of feeds</em>
