Answer:

y=2x-3

Step-by-step explanation:

y=mx+b

Where m is the slope and b is the y intercept

Slope is rise over run, the line is up 2 over 1

And the point of the line where it meets the y axis is -3. so b is -3

Solve the system of equations: 10x + 7y = 49 and 10y – x = 70

jekas [21]

10x + 7y = 49
10y – x = 70 so x = 10y - 70

substitute x = 10y - 70 into 10x + 7y = 49
10x + 7y = 49
10(10y - 70) + 7y = 49
100y - 700 + 7y = 49
107y = 749
y = 7

x = 10y - 70 = 10(7) - 70 = 0

answer
(0, 7)

Can any anyone help me with this problem please Solve : 2x - 1 = 7

ziro4ka [17]

Answer:

$x = 4$

Step-by-step explanation:

Solve for $x$ :

$2x - 1 = 7$

-Add both sides by $1$ :

$2x - 1 + 1 = 7 + 1$

$2x = 8$

-Take $2x$ and divide it on both side of the equation:

$\frac{2x}{2} = \frac{8}{2}$

$x = 4$

So, the value of $x$ is $4$ .
