How do you solve equations by substitution​

Mathematics
1 answer:
Jet001 [13]3 years ago
4 0

Answer: The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Step-by-step explanation:

Please help ASAP!! I'm in. a google meet rn and need to prove I got this question right

Answer:

x = 5.4

Step-by-step explanation:

(This question has already been answered, but both of the incorrect ones were deleted, so for future reference...)

Fig A is a scale image of Fig D. These two quadrilaterals are similar, and thus, the side lengths of corresponding sides are proportional. Set the proportion x/3 = 7.2/4 (you could alternatively write it as x/7.2 = 3/4 but for the simplicity's sake, and assuming anyone who has this problem would already know how to solve proportions like these...)

7.2/4 = 1.8

so

x/3 = 1.8

now multiply both sides by 3 to get x = 5.4
