Answer:

J+B+T=105

Step-by-step explanation:

B is 4

so 4 plus 4 plus 4 equals 12

T is 1

so 1 plus b which is 4 equals 5

J is 100

100 -T

100-1 equals 99

Answer:

Step-by-step explanation:

B + B + B = 12kg

3B = 12kg divide both sides by 3

B = 4kg

Substitute to T + B = 5kg:

T + 4kg = 5kg subtract 4kg from both sides

T = 1kg

Substitute to J - T = 99kg:

J - 1 = 99kg add 1 to both sides

J = 100kg

Therefore:

J + B + T = 4kg + 1kg + 100kg = 105kg

1. Which would be a more helpful for solving the system: adding the two equations or subtracting

ira [324]

Answer:

1) Subtracting one from the other

2) x = 0.375 and y = 0.125

Step-by-step explanation:

Equation 1 :

$\frac{2x+1}{2y}=7\\\\$

Equation 2:

$\frac{6x-1}{2y}=5$

To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,

$\frac{2x+1}{2y} =7\\\\2x+1=14y\\\\Multiplying\ Equation\ 1\ with\ 6\\\\12x+6=84y$

Now for the second equation:

$\frac{6x-1}{2y}=5\\\\6x-1=10y\\\\Multiplying\ equation\ 2\ with\ 2 \\\\12x-2=20y$

Now subtracting equation 2 from equation 1

$12x+6=84y\\\\12x-2=20y\\\\Subtracting\ leads\ to\\12x-12x+6-(-2)=84y-20y\\0+8=64y\\8=64y\\8/64=y\\0.125=y$

now insert this value of y into any equation

lets insert it into equation 1

$\frac{2x+1}{2y} =7\\\\2x+1=14y\\2x+1=14(0.125)\\2x+1=1.75\\2x=1.75-1\\2x=0.75\\x=0.75/2\\x-0.375$
